LCD is the abbreviation of liquid crystal display. The structure of LCD is to place liquid crystal in two pieces of parallel glass. There are many vertical and horizontal small wires between the two pieces of glass. Through the power on or not, the rod-shaped crystal molecules can be controlled to change the direction, and the light can be refracted to produce a picture. Much better than CRT, but the price is more expensive..... LCD projector is the product of the combination of LCD display technology and projection technology. It uses the electro-optic effect of liquid crystal to control the transmission and reflectivity of the liquid crystal unit through the circuit, so as to produce beautiful images with different gray levels and up to 16.7 million colors. The main imaging device of LCD projector is LCD board. The size of LCD projector depends on the size of LCD board. The smaller the LCD board is, the smaller the projector is..... According to the electro-optic effect, liquid crystal materials can be divided into active liquid crystal and inactive liquid crystal, in which the active liquid crystal has high light transmittance and controllability. Liquid crystal panel uses active liquid crystal, people can control the brightness and color of liquid crystal panel through relevant control system. Like LCD, LCD projector adopts twisted nematic liquid crystal.... The light source of LCD projector is a special high-power bulb, and its luminous energy is much higher than that of CRT projector, so the brightness and color saturation of LCD projector are higher than that of CRT projector...
